Wegener observed that that coastlines of continents in the southern hemisphere had similar grooves. which of the following supports coastlines far away from one another having similar grooves? animal extinction glacial movement rock formation human interactionc

B, glacial movement.

Wegener observed similar grooves along the coastlines of continents in the Southern Hemisphere. These grooves were created by the movement of glaciers. Glaciers generally move in one direction. This movement creates large scratches in rock structures.

When continents are placed together, you can observe that the glacier scratches match up. They move from one continent to another.

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
